The application fields of vacuum coating machines are different, the coating workpiece and coating layer are different, and the coating technology used is different. If only pure metal is coated, we can use DC magnetron sputtering technology. If coating insulating targets, I may There are many radio frequency magnetron sputtering technologies. For example, if only some conventional decorative products are coated, then we can use resistance evaporation coating technology, etc. If so many coating technologies are used, what if the effect and quality of the vacuum coating machine coating machine can be ensured? The following is a collection of vacuum editors. How can I ensure the coating effect and quality of the vacuum coating machine?

         Vacuum coating machine coating mainly refers to a type of object substrate that needs to be coated under a higher vacuum degree. Then when plating different substrates and targets, the coating technology used is different, and the attention to details is also different, such as the selection of target materials, size, shape, target energization voltage, plasma energization current, including The distance between the target and the substrate, as well as the placement position, will affect the effect and quality of the coating. During the coating process, in order to ensure the pure coating of the coating layer, we also need to clean the surface of the substrate to remove the residual substances and gas pressure on the surface of the substrate, which has a great influence on the coating effect and quality. The target and substrate to be plated are different, the coating technology is different, and the focus is also different. These considerations are more in-depth.
        For engineers who generally operate a vacuum coating machine, they may not consider it so in-depth, and may consider some simple and external factors. For example, there is dust on the surface of the coated material. After the vacuum coating machine has been used for a period of time, the equipment must be cleaned and maintained. Standardize operators and operating requirements, including wearing professional clothing, gloves, foot covers, etc. Strictly handle the substrate material to make it clean and meet the process requirements. The source material meets the necessary purity requirements. Ensure that facilities, equipment and operating environment are clean. Such as material, sample placement environment requirements, ambient temperature and humidity requirements, etc. Reduce the low indoor air mobility of vacuum coating equipment, minimize the intrusion of outdoor dust, etc.
